MmING-TUMBLER.

Specification of Letters Patent.

Patented Apr. 6, 19115.

Application filed March 25, 1913. Serial No. 756,785.

To all whom it may concern:

Be it known that I, HERMAN A. SEIFKE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new edge. Therefore bartenders and others mixing such drinks have to use a tumbler of twice the size of that which would otherwise be necessary. 7

The object of the present invention is to provide a mixing tumbler of such shape that 'itmay be of comparatively small size.

In the accompanying drawing, Figure 1 is a broken side elevation of my improved mixing vessel, and Fig. 2 is a plan view thereof.

Referring to the drawing, 1 indicates my improved mixing vessel, which is preferably made of glass, and in generalappearance resembles an ordinary large glass tumbler.

The inner surface of the wall of this tumvessel.

bler is formed with one or more, two being here shown, of vertical inwardly extending ribs 2, each rib having a front face 3, in a substantially radial or normal plane, and a rear face 4, making a considerable angle with a normal to the side of the vessel.

When liquid under pressure is discharged into such a vessel to 'mix with other liquid or liquids previously poured thereinto, instead of the liquids rotating freely in the vessel, and thus commingling with each other very imperfectly and slowly, said liquids repeatedly impinge against the square front faces 3 of the ribs 2, and are thereby defiect ed inwardly or toward the center of the vessel, and caused to rapidly intermingle with each other. Also with this construction or mixing vessel a much larger amount of liquid can be mixed for a given size of the I claim An upwardly flaring open-topped glass mixing tumbler having an integral upwardly directed rib extending inwardly from its inner wall.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

HERMAN A. SEIFKE.
